Hack Chat 0x01: Introduction to Laser Cutter
Steag Center For Smart City Technology is organizing Hack Chat regarding Laser Cutter. The Center is equipped with 150W C02 Laser cutter and Engraver,
In the session, we will look into the working principles and operation workflow the laser machine for cutting and engraving.
The Session exclusively for the Rajagiri School of Engineering & Technology students.
Date: Feb 6th 2020
Time: 5:00 PM to 5:30 PM
Venue: Steag Center For Excellence in Smart City Technologies, KE Block Extension RSET
Note: The Session exclusively for the Rajagiri School of Engineering & Technology students.
What is Laser Cutter/Engraver?
Laser cutting is a technology that uses a laser to slice materials. While typically used for industrial manufacturing applications, it is also starting to be used by schools, small businesses, and hobbyists. Laser cutting works by directing the output of a high-power laser most commonly through optics. (Wikipedia) .
CO2 (Carbon dioxide) Laser?
The carbon dioxide laser (CO2 laser) was one of the earliest gas lasers to be developed. It was invented by Kumar Patel of Bell Labs in 1964, and is still one of the most useful. Carbon dioxide lasers are the highest-power continuous wave lasers that are currently available. They are also quite efficient: the ratio of output power to pump power can be as large as 20%. The CO2 laser produces a beam of infrared light with the principal wavelength bands centring on 9.4 and 10.6 micrometres (μm). (Wikipedia)

Really insightful on how to use the laser cutter, especially in projects based application
Thanks Salman :)
flat end leaves flat surface profile on the stock and are good for removing large volume of material, but steps are formed when used for making curved surfaces. Ball end leaves curved surfaces and forms smooth curved finish while cutting cavities. They are used for finishing cuts.
Upcut & Downcut
In an Upcut type end mill the teeth on the flute will point upwards. This means that the end mill is cutting and drawing out the wood through the flute. This is good for cutting deep into the stock. But this leaves a bad surface finish on the top of the surface.
A downcut type end mill has teeths that point downward on the flute. This means that the end mill will cut and try to push the material into the stock. This will give good surface finish on the top, but it is not very efficient at removing material.
Drill bit Vs Endmills: A drill bit needs to cut straight into the material hence will have teeth at tip. But an Endmill needs to cut from the sides also, that means it needs to have a cutting edge spiralling all the way up to the flute.
Bit material: Router bits used in Shopbot are made from a variety of materials such as solid carbide, carbide-tipped steel, and high-speed steel.
Flute type: There are four basic flute types: Straight, spiral up-cut, spiral down-cut, and compression
